A new family of BODIPY analogues (BDB1-8) derived from benzothiazole-pyrimidine-based bidentate ligands was synthesized and fully characterized. The photophysical properties of these boron complexes were measured both in solution and solid-state. These new luminophores exhibited intense fluorescence with high quantum yields ranging from 0.27 to 0.79, and moderate Stokes shifts ranging from 660 to 2120 cm in solution. Due to the existence of strong intermolecular interactions, BDB1-8 showed quenched fluorescence with low quantum yields ranging from 0.03 to 0.20 in solid-state. In addition, BDB1 and BDB2 were capable of sensing cysteine in aqueous solution with high selectivity and sensitivity, which means that these complexes hold great potential in serving as fluorogenic cysteine sensors for biological application.
合成并全面表征了一类基于苯并噻唑 - 嘧啶的双齿配体衍生的新型BODIPY类似物（BDB1 - 8）。在溶液和固态中测量了这些硼配合物的光物理性质。这些新型发光体在溶液中表现出强烈的荧光，量子产率高，范围为0.27至0.79，斯托克斯位移适中，范围为660至2120 cm⁻¹。由于存在强分子间相互作用，BDB1 - 8在固态中表现出荧光猝灭，量子产率低，范围为0.03至0.20。此外，BDB1和BDB2能够在水溶液中高选择性和高灵敏度地传感半胱氨酸，这意味着这些配合物在作为用于生物应用的荧光半胱氨酸传感器方面具有巨大潜力。
